N-(Alkylidene or arylidene)-2-substituted-2-propenylamines were regiospecifically functionalized into novel N-(alkylidene or arylidene)-2-alkoxy-3-bromo-2-substituted-propylamines, which were proven to be excellent sources for 3-alkoxyazetidines through sodium borohydride reduction of the imino bond and subsequent intramolecular nucleophilic substitution.

N-(Alkylidene or 1-arylmethylidene)-2-propenylamines were regiospecifically functionalized to novel N-(alkylidene or 1-arylmethylidene)-3-bromo-2-fluoropropylamines, which were proven to be excellent precursors for 3-fluoroazetidines.
